GasSLX Shocks – Adjustable Commercial Truck and Trailer Shocks (89000 series) - The three position GasSLX™ adjustable shocks absorbers by Gabriel® allow you to choose from one of three settings – Firm, Regular and Extra Firm – to match different applications. The GasSLX shock incorporates a gas cell design, creating a physical barrier between gas and fluid, preventing aeration which can cause fade, or reduction in damping force. This gas cell technology is a full-life feature and is better suited for longer-life commercial vehicle applications. And like all Gabriel shocks and struts, GasSLX shocks feature a super-finished chrome piston rod for superior corrosion resistance and a leak-proof piston seal which extends product life. Advanced gas cell technology improves gas retention and provides more consistent high temperature operation. Unique pressurized piston seal design reduces force-velocity variabilities and self compensates for wear.
